Following distance and stopping
Leaving enough space to stop is one of the simplest ways to avoid a collision. The G1 test expects you to know how to measure and adjust your following distance.
Key facts to remember
- ◆ Keep at least a two-second gap to the vehicle ahead in good conditions.
- ◆ Double the gap to four seconds or more in rain, snow, or fog.
- ◆ Total stopping distance is your reaction distance plus braking distance.
- ◆ Stopping distance grows sharply as speed increases.
- ◆ Tailgating gives you no room to react if the vehicle ahead brakes suddenly.
